You can only abuse it as long as you have points. With Reddit (or systems like it) you have no limits - for instance, you could upvote all content on the front-page every hour. On the other hand, with this Kudos system, you would run out of points rather quickly if you did that. I agree, as others posted in this thread, that there are many other problems that need to be addressed. Frankly I don't know if a p2p network system can even be built to address all issues - social voting networks based on reputation are rather complex. However I hope to have shed the light on some interesting properties that can be achieved by combining the decentralized aspects of DHT keys, with the consensus features of a blockchain. Moreover, the idea of of using cryptocurrency tokens, for things other than currency, is a field that needs to be explored more.
